Needy people in San Francisco will get food if Green Bay Packers linebacker Clay Matthews sacks 49ers quarterback Colin Kaepernick this Sunday. Just how much food they get, will be determined by how many times Kaepernick goes down.

Campbell’s Chunky Soup is donating 1,000 cans of soup to the San Francisco Food Bank, and 1,000 more in Green Bay for each sack Matthews records against a 49ers quarterback. The “Sacks for Soup” program will benefit food banks in Green Bay and each opponent’s city throughout the NFL season.

Matthews was only able to sack Kaepernick once in the NFC divisional game won by the 49ers last season. The Packers’ linebacker was credited with 2.5 sacks on Alex Smith in week one of the 2012 season, though. The 49ers defeated the Packers in both of those games.

As part of the program, Campbell Soup Company will also be donating $1,000 to Matthews’ CM3 Charitable Fund, for each sack he records this season. Matthew’s is starring in this year’s Campbell’s Chunky Soup “Mama’s Boy” ad campaign.
